It should reference MOF/UML.
The reference to SBVR should be more specific - at least to the OMG spec page http://www.omg.org/spec/SBVR/, if not a document number - depending on whether it's dependent on a specific version of SBVR (I suspect it is).
References to commercial dictionaries are not appropriate since I presume any text is copied into this spec, and people do not need to access the dictionary to use/understand the BMM spec.
